IMPROVEMENT IN SOAP-FRAMES.

Specification forming part of LettersPatent No. 178,394, dated June 6,1876; application filed 1 October 16, 1875.

To all whom it may concern:

Be it known that I, DANIEL WHITAKER, of Boston Highlands, Boston, in thecounty of Suffolk and State of Massachusetts, have invented a new anduseful Improvement in Soap-Frame, of which the following is aspecification:

Figure 1 is a top view of my improved soapframe, partly in section, andpart being broken away to show the construction. Fig. 2 is a side viewof the same, partly in section, through the line atm, Fig. 1. Fig. 3 isa cross-section of the same, taken through the line 3 3 Fig. 2.

Similar letters of reference indicate corresponding parts.

The objectof this invention is to furnish to manufacturers a soap-framewhich, although simple in construction, shall be adapted to be moreconveniently set up and taken down, and its side and end plates orpieces more firmly connected or locked together, than others of itsclass.

To these ends the base of the frame is made in three parts, secured toeach other by transverse screw bolts or rods, whereby. they are adaptedto clamp the bottom edgesof the sides of the frame; secondly, the bottomedges of the end portions of the frame are adapted to enter grooves inthe base of the frame, and are attached thereto by hooks and staples insuch a manner as to permit their convenient detachment; thirdly, the endportions of the frame have clamping-bars attached, whereby they may belocked to the sides, in such a manner as to hold the ends vertical, andform a tight joint between them and the sides; and, lastly, the sideportions of the frame are provided with truss-like braces, whereby theyare .prevented from buckling, warping, 850.

The frame is mounted upon a small truck, A, for convenience in moving itfrom place to place. Bis the base of the frame, which is made in threeparts or piecesa wide center piece and two narrow side pieceswhich areheld together by two or more bolts, 0, which are passed throughfthemtransversely, and have hand-nuts G screwed upon their ends. D are theside'iplates, which are made ofplateiron, and the lower edges of whichare inserted between the parts of the base B, where they are clamped bythe bolts 0. The upper edges employ them in practice, principally forthe reason that they cover less of the surface of the side plates D, andthe radiation of heat is hence facilitated, which is a matter ofconsiderable practical importance in respect to the cooling andsolidifying of the plastic mass contained in the frame. Thesetruss-braces D are a material improvement upon the wooden and metal barsheretofore employed, since the former of these are liable to becomewarped or bent, besides being cumbrous and otherwise objectionable,while cast-metal barssuch, for example, as shown in Patent No.63,898-'-have proved too heavy and expensive to meet with other thanlocal adoption and use. My improved braces combine strength, lightness,and cheapuess in a high degree, and.have hence proved superior inpractice.

The end edges of the side plates E are bent inward at right angles tooverlap the end boards G, the lower ends of which are inserted incross-grooves formed in the middle part of the base B. The inner edgesof the lower ends of the end boards G are rounded off, as shown in Fig.2, so that their upper ends may be swung outward and the boards removedwithout marrin g the block of soap; The end boards G are held down byhooks H, attached to their lower parts, and which hook into eyes orstaples I, attached to the middle parts of the base B. The end boards Gand the side plates D are drawn and clamped together by the bars J,which turn in keepers attached to the end boards G, and the ends ofwhich are bent near- 1y at right angles, to overlap the end parts of theside plates D, to draw them snugly against the side edges of the endboards G, and hold them securely in place. The said bars likewise drawthe end boards G firmly against the flanges of the side plates D, byreason of being secured by keepers, as above stated. The said end boardsare thereby held vertical, and

a tight joint formed between them and the' to each other by bolts andnuts 0 c, to adapt them to serve as clamps for securing the lower edgesof the side plates D, substantially as herein shown and described.

2. The end boards G, having their lower ends rounded off upon the inneredge, and secured in cross-grooves in the middle part of described.

the base B by hooks H andeyes or staples I,

substantially as herein shown and described.

' 3. The combination, with the end boards G and side plates D, havinginward flanges formed on their ends, of the clamp-bars J, the same beingattached to said end boards by -means of 'ke'epers, as shown anddescribed.

4. The combination, with side plates D, of metal braces or trusses E,riveted thereto at their ends, the blocks or filling F, and screwbolts,having their heads countersunk on the inner side of said plates, all asshown, and
